When Memory Devices Get TOO Small

I bought a used (barely) Svbony SC311 astrocamera. These are cameras made only for astrophotography.  They are very light and can talk directly to your phone so you can adjust settings on the fly and record (I think) directly to your phone via WiFi. In any case, it will record to the microSD card that goes in the slot. But seems not to have stayed in the slot when I picked the SC311 off the desk where it was charging and walked to the easy chair where Rosie insists on sitting on my lap. I am not blaming this very loving dog. I believe I lost the microSD card before I reached the chair. 

These cards are tiny. I still do not see it on the floor anywhere. Amazon is promising delivery of a larger one tomorrow, 128GB, not physically larger.
